In fact, it's not better all around, and you can check out the follow-up video I've already uploaded. The TSDZ8 is currently cheaper and I think the TSDZ8 would be better if you only consider the product level. Of course, the TSDZ8 doesn't give the kind of ample instant power that the BBS02B does.

Hi there,are you using a press fit centre shaft from a shimano BB92? The inner diameter may be 41-42mm, if so you will need to add a sleeve. Regarding the chainring video, I think I'll make an instalment soon explaining it, including recommendations for currently available chainrings with offsets.

Hi, @@varstromebikeconversion5837 Finnaly, i don't really know if my bottom bracket is pressfit or not ... on the internet I find contradictory information, and on the manufacturer's website I find nothing concrete! probably many variant produt with the same name ?! idk Anyway this video can be a really good idea for sure ! A video explaining what offset we need for what situation can be great too ... for my parts, i think the 44T maybe don't fit on my bike, the theeth of the chainring probably going to hit the body of my bike (or going to be tooooo close to it) and i'm not sure what chainring i have to choose :( So this can be a good idea for helping massive people. i'm waiting your videos ^^

Hi, you can check out my link which is the instructions. If you still don't know how to do it, I can create a quick short video to teach you.

O efeito de limitação de velocidade do ecrã não é, de facto, muito útil, pois depende, em última análise, do controlador. A lógica de limitação de velocidade do ecrã é basicamente a mesma, que modelo de ecrã está a utilizar atualmente?

The fat bike is just one factor, probably you also need to take into account the terrain you are travelling on, your weight, your load capacity, your driving habits (whether you like to keep hitting extreme speeds or enjoying the scenery in a smooth manner). Many times I think 750W is enough, but some people will prefer the punch of 1000W (rated power).

@@varstromebikeconversion5837 so yes?

@@pietroonly10 yes you may try it

I've ridden 300KM and feel good, I don't think we need to have too much "carbon fibre anxiety": )

Hi for the scott aspect 960,the BB is the BSA73 and suitable for the mid drive motor, that means you can install both Bafang BBS or Tongsheng TSDZ 2B/8,it depends on your needs.

@@varstromebikeconversion5837 WITCH ONE woul u pick tonsheng or bb for scott aspect im after the 750 bafang use it basicley allround bike bit in the woods and long cruiz bro name the kit i should buy gonna order it let store custumer bike mount it up thats what they told me ;)

Hi for the batteries from the Bafang,do you mean the Bafang is made by Bafang?if so ,they have their own battery protocols, so it can't be work together

@@varstromebikeconversion5837 Thanks for the reply. I am sorry, I meant a Jumbo Shark battery that works with my Bafang motor. I think i figured out that it would indeed work with Tongsheng too.

Yes, if I had to choose, I'd go with the TSDZ8, the torque sensor has more advantages than the speed sensor. But the TSDZ8 has a poorly tuned controller, I plan to work out an optimal controller algorithm and test it.

@@varstromebikeconversion5837 Yes, software is not optimized, but it is getting there. I just bought Jlink v9 programmer, but still had no time to play with it. There are several beta firmware versions available on the facebook group. But of someone should provide/develop something like OSF, that would be the best scenario. I mostly use level 2 and 3, have no need for other levels with this firmware.

Yes, after all, BAFANG BBS has been on sale for almost 6 years, it's certainly a mature product. But it has had very few updates, I wish it could be upgraded for the durability of the hardware inside as well as the waterproofing, unfortunately this can only be done by the dealer. The TSDZ8 is a product that's been on sale for almost 2 years now, and it's going to take a while to be certified in the marketplace. But as far as functionality is concerned, for the same price I'd prefer a torque sensor motor if I could get one (even though TONG SHENG's torque sensor isn't very well tuned, it can be programmed to be modified)

Adiós a las alegrías del bricolaje, de instalar, explorar y reparar uno mismo. Por supuesto, los proveedores también deberían cumplir sus promesas de garantía. Espero que pueda utilizarlo normalmente después de la reparación está terminado, si hay algún problema, también puede preguntarme, he reparado motores BAFANG durante 5 años y tienen una rica experiencia.

That's cool, I hope everything goes well with your installation and testing, and you can always ask me if you have any questions!

Yes, I'm just still waiting on the postal tracking information. Will certainly keep in touch for how things are once its received 👍

Hello again! Still awaiting my tracking information can you please assist with this ?

@@RozWood-fx3iy could you please provide the order ID to me so that we can check for you?

@@RozWood-fx3iy Hi could you please provide the order ID to me so that i can check for you?

Hi yes, as far as we are concerned, we sell the TSDZ8 with a selection of replacement parts on hand to provide after-sales service.

If you are looking for flywheel performance and use a normal chain ring and crank, it can support up to 9 speeds, and once it is larger than 9 speeds, the chain will be at risk of falling off. If you use chain ring and crank with offset, it can support 10 and 11 speeds. 11 speed is the theoretical limit.

Hi, it depends on how you use it and the scenario in which you use it. Scientific usage and low stress usage scenarios will prolong the life of nylon gears. For example, if your cycling habits are aggressive, often accompanied by strong acceleration and deceleration, or if you often need high torque for climbing, the life of the nylon gears will decrease very quickly. I've found customers who have had to replace nylon gears after 500 miles of riding (he's a delivery guy). So there's not really a standard answer to this, but my advice is that having one or even more nylon gears on hand (buying more than one tends to be a better deal) is absolutely right, and my general recommendation is to check them from 1250 miles onwards, but if you don't notice any unusual noises, it's not really a matter of special concern.

Unfortunately, TONG SHENG doesn't give this data, so I will test it and expect to give you an answer today or tomorrow.

thank you so much

Hi, sorry for the inconvenience, we are able to send from China to Thailand, did you contact customer service at varstrom.com?

Thank you for responding. Yes I did, customer service link off the varstrom website..

Is it possible to contact you direct somehow to then ask some questions regarding product details, cost and delivery timescale. Thank you.

@@RozWood-fx3iy do you have whatsapp?if so,we could probably communicate on whatsapp.

Yes I do have WhatsApp. Can you provide yours somehow please.

Yes, it's every customer's desire to get a product that combines low price, stability, comfort, high performance and high quality, but at the same time it's hard to have it all. In my opinion, the quality and construction of the internal parts of both the BBS and TSDZ8 are in the middle of the range, away from the high or top level, which means you need more frequent regular maintenance. Adding grease is a must, followed by regular replacement of failed fittings, depending on how often you use it, the frequency might be 6 months if you are an outfitter, or typically 1-3 years for normal use.

Of course you can, if you have batteries, or have a preferred battery supplier, all you need to do is buy the motorkit, which we have on our website: www.varstrom.com, and for youtube followers, we have an additional offer, just contact our customer service to claim it.

​@@varstromebikeconversion5837 Thanks, I am one of your you tube subscriber and I hope l get the offer .😊😊😊

Thanks,I am one of your you tube subscriber and I hope I get the offer.😊😊

@@Roben12345 You can contact the seller from www.varstrom.com to get better offer.

Thanks for your good response.

My pleasure

Yes, this requires the use of OSF, which is in what I plan to make a video about, I'm waiting for this cable to arrive and will then make an instalment of the video. I'll let you know once the video is updated.

@@varstromebikeconversion5837 Nobody knows if the OSF is even compatible for now, do you have seen other results?

@@matthiasschuster9505 Hi, you can check out this URL first:ebikestuff.eu/pl/uslugi/266-1628-usluga-wgrania-otwartego-oprogramowania-open-source-tsdz2-tsdz2b-osf.html#/77-oprogramowanie-open_source_pod_oryginalne_wyswietlacze

There is no OSF for TSDZ8. Also programmer is different from TSDZ2B, J-Link v9.

varstrom.com is the website (shop) that you can find the conversion kits.

Do you know the internal gear ratio of the tsdz8?

@@wrosslandwr8032 sure,it is 38

❤️

sorry for the delay,i will update in 1-2 days

Hi, sorry for the delay, we expect to release it within the week. Regarding the Toseven, we will be purchasing one as soon as possible and expect to release a comparison video in June.

That's definitely a good suggestion, as far as I know TSDZ8 has not developed a motor that adapts to the BB 92mm and can't be solved with shims, I'll check with TONGSHENG to make sure that they are going to do it in the future.

@@varstromebikeconversion5837 thank you for your reply. I found solution, I designed the adapter and it was cut from stainless steel, it works great. I can enjoy the tsdz8 on my bike

@@hlkification I'm sorry, I can't believe I forgot that you can DIY the centre shaft! Yes, DIY can spark a lot of creativity and inspiration, I'm guessing you extended the motor centre shaft, right?

Hello, sir. I'm sorry I've been travelling and I'm just back now. About the TSDZ8 you need from UK stock, we have stock in the UK and can ship it to you via DPD, it is expected to arrive in 1-3 days, if you need it, you can go into our website to buy it: www.varstrom.com And tell the customer service staff that you are coming from our official RUclips channel, he will offer you a discount.

@varstromebikeconversion5837 thank you , i ordered a motor from you and it arrived literally next day , amazing fast delivery

@@darrennorthall9774 It's great, I hope you enjoy it and feel free to ask me any questions you may have.

Hi yes ,we done it,will update in 2-3 days

Thank you very much for your support. Regarding the performance comparison, I will show it in the next video, which is expected to be at the end of April. About display compatibility, I can tell you now first, the list of 4 displays supported by TONGSHENG TSDZ8 at the moment 1. 500C (we can be compatible with tongsheng by brushing the firmware before shipping) 2. 810S (we have set it in the factory and can use it directly) 3. EKD01 (we can make it compatible with tongsheng by brushing the firmware before shipment) 4. SW-M58 (we have set it in the factory, you can use it directly)

@@varstromebikeconversion5837 That is a great answer, thank you! Do you change software on display itself or is it within TSDZ8 controller? In the video about displays, please go over the functionality of each one: What data can be read, how to adjust the wheel size etc.

@@ukrytykrytyk8477 Sorry I overlooked this comment, very sorry. There is an OSF programming software that can program the controller, it has to be programmed, using display can only make limited adjustments. I guess there is also a need for a video of these 4 displays in action, I'll take the time to film it.

That's weird. Do you have the instructions? I can provide you with one, it could be a firmware issue.

It is not quick release bracket. You can change the disppla to mph.

Hi, sorry to reply to you after a year, I realise I've overlooked some comments, have you heard of the display P860C-ML? We have made some improvements on this display so that the display can be seen more clearly in sunlight.

@@varstromebikeconversion5837 Yes I wasted $120 on the P860c display; still can not see it in the sun.. works great at night.. but i do not ride at night. Garmin Edge uses the Sunlight Readable TFT displays that make the map appear to float above the glass display.. That TECH could be used in Ebike displays.. and there are plenty of riders that would pay the extra amount to be able to see WATTS. SPEED, VOLTAGE etc... I have the Garmin Edge 1030 PLUS, and i can see it very well i the sun.. Actually better in direct sun light hitting the display..

Mine came the same way, I'm trying to look up if there's a firmware upgrade. Does your display say Varstrom or Intelligent? Mine says Varstrom.

@@UnsatGoUA my display Varstrom here is in the sunlight, the visibility is very poor, I am not satisfied with this display

I also have this controller with a bafang mod 750 and also there is no selection of sport normal as well as temperature

You need to enter the default password of 100001 to unlock the speed governor. I am eager to see what the top speed is with my Bafang BBSHD 1000 watt motor but I am not really interested in speed I need serious high climbing where I ride. I have a 52 volt LiFePo4 battery with 25 amp/hour capacity so I am hoping for some significant range without a recharge.
